The EM Log Parser has recently been updated and now includes support for the up and coming 8.5 release. For those that don't know the Log Parser is a tool for diving into EMUser and EMUserLogoff logs. It will show you which actions, conditions, and nodes ran in your session and which ones were successful and which failed at a quick glance and also show you the duration that each item took including desktop settings and session data. It is by far the best tool for troubleshooting EM policy.
